For the manufacturing of enzymes it is importance to customize the fermentation media ingredients to the type of enzyme produced and to the host in which the enzyme is produced. The production is highly influenced by the components present in the medium at the moment production is induced. Kerry supplies specially developed media ingredients to boost the growth during the growth phase in submerged fermentations with microorganisms such as Streptomyces and Bacillus.

When recombinant hosts are used, the host and the expression system determine the nutritional needs. Kerry has a special portfolio of Hy-Express™ total nitrogen source solutions targeted towards specific hosts and suitable for the expression system specified.
